Hi All,
I am developing a RIFE web application that I am trying to unit test.
When my surefire tests run, RIFE is unable to load Java classes properly.
Here is the related portion of the pom.xml:
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<excludes>
<exclude>**/SACBaseTest.java</exclude>
</excludes>
<systemProperties>
<property>
<name>rife.webapp.path</name>
<value>${basedir}/target/classes</value>
</property>
</systemProperties>
</configuration>
</plugin>
</plugins>
<testResources>
<testResource>
<targetPath>/</targetPath>
<filtering>false</filtering>
<directory>${basedir}/src/main/webapp/WEB-INF/classes</directory>
<includes>
<include>**/*</include>
</includes>
</testResource>
</testResources>
</build>
Before I explain the problem, here is a part of the stacktrace:
com.uwyn.rife.engine.exceptions.ElementImplementationInstantiationException:
The implementation 'net.collab.extranet.sac.elements.SACHome' of element
'manual:SACHome' couldn't be instantiated.

So...a little information about the structure. When my Maven application
runs the tests, the target directory looks like this:
target
/classes
/test-classes
/sites
/rep
/templates
RIFE can successfully load the sites/main.xml but RIFE then starts to
instantiate the SACHome object. This object is compiled to target/classes
but RIFE cannot find it. RIFE developers tell me that RIFE's ClassLoader is
being circumvented or is using the same classpath as what the surefire tests
are. How can I get my tests, which include RIFE's engine, to have the same
classpath? I've done everything I can think of. Just to show you all the
surefire classpath:
[DEBUG] Test Classpath :
[DEBUG] /Users/jwhitlock/work/sac/src/web-app/target/test-classes
[DEBUG] /Users/jwhitlock/work/sac/src/web-app/target/classes
[DEBUG] /Users/jwhitlock/work/sac/src/web-app/target/classes
[DEBUG] /Users/jwhitlock/work/sac/src/web-app/target/test-classes

jdk15-1.5.1.jar

[DEBUG] /Users/jwhitlock/.m2/repository/commons-io/commons-io/1.2/commons-
io-1.2.jar
[DEBUG] Adding to surefire test classpath:

[DEBUG] Adding to surefire test classpath:

booter-1.4.jar
[DEBUG] Adding to surefire test classpath: /usr/local/maven-2.0/core/plexus-
utils-1.1.jar
As you can see, target/classes and target/test-classes are both on the
classpath and should allow RIFE to be able to load classes from
target/classes but is not able to do so.
Take care,
Jeremy
